Collapse ModifierStack and keep instances

rartidiello — Fri, 12 Mar 2021 02:39:14 GMT

Hi,

I need a script for collapsing the modifier stack of all selected objects. Right now the Collapse button under the Utilities panel works but loses the instances.

Thanks.

something like this...

fn collapseNodes nodes = ( for node in nodes do maxops.collapsenodeto node node.modifiers.count off ) /* collapseNodes selection */

or this...

mapped fn collapseNodeToBase node = (maxops.collapsenodeto node node.modifiers.count off) /* collapseNodeToBase selection */

Can these be updated to work on 2024?

what is not working in 2024?

I select one object with 'Select Dependents' enabled:

Which selects 185 objects.

I save the script as a .ms file:

I run the script

...and nothing at all happens, with either of the scripts. Am I doing something wrong? 🤔

This is the modifiers stack of the objects:

Ideally, I would want to convert all those 185 objects to 'Editable Mesh', but preserving instances.

first of all the executable code looks as:

for node in selection do maxops.collapsenodeto node node.modifiers.count on

second, dependent nodes are not exactly instances. There are other mechanics to find all instances of a node.

and third, if you do everything right, I'm pretty sure it will still work in 2027 at least.

Using 'Edit - Select Instances' didn't work either.

But this other script did:

if selection.count != 0 do

(

local firstInstances = #()

for o in selection do

(

InstanceMgr.GetInstances o &firstOnly

if firstOnly.count > 1 do

append firstInstances firstOnly[firstOnly.count-1]

)

if firstInstances.count != 0 do select firstInstances

)

for obj in $ do

(

addModifier obj (Edit_Mesh())

)

for obj in $ do

(

maxOps.CollapseNodeTo obj 1 off

)

Thanks anyway.

Great if the code above works... Good luck either way.
